Jordan Henderson sale not ruled out by Liverpool boss Jurgen Klopp

Liverpool boss Jurgen Klopp says he is prepared to sell any player who is not happy amid reported interest from Tottenham Hotspur in Jordan Henderson.

Henderson, 25, was one of Liverpool's most important players under Brendan Rodgers and inherited the club captaincy when Steven Gerrard left last summer.

But the England international has not looked as comfortable in Klopp's midfield after the former Borussia Dortmund boss replaced Rodgers in October.

"Everything is OK in this moment but nobody in the world, maybe only [Lionel] Messi, is unsellable," Klopp told reporters. "There is always a situation.

Jordan Henderson joined Liverpool from Sunderland in 2011.

"I come from a club where always the best players are picked by other teams and at the end, you have to accept a few things and always need to have a Plan B or C.

"I am pretty sure it is only a rumour [Tottenham wanting Henderson] but if not and if a player -- let's not say Hendo but any player -- comes to me and says he doesn't feel comfortable and wants to leave, style of play, more money, then you always have to start thinking. That's all I can say on this.

"Coutinho, [Roberto] Firmino, so many players are very special. You could go through the whole squad. But if a player wants to go to another club then I'd always be open to it because I don't want to have a player in my squad who doesn't want to be in the squad.

"These are problems you don't need during a season. A player is never good enough for you to have to cope with problems like that for an entire year."
